Heaven's Lost Property the Movie: The Angeloid of Clockwork

Sora no Otoshimono the Movie: The Angeloid of Clockwork (劇場版 そらのおとしもの 時計じかけの哀女神（エンジェロイド）Gekijouban Sora no Otoshimono: Tokeijikake no Angeloid), also know as Heaven's Lost Property: A Clockwork Angeloid, is an animated movie based on the manga and anime "Sora no Otoshimono". It was released on June 25, 2011 in Japan and was directed by Saitou Hisashi. It was released on DVD on February 24, 2012.

The film opens with Tomoki and the rest of the New World Discovery Club in the middle of another unusual, if not typical, situation. A giant chicken, whom Tomoki apparently forgot about, wreaks havoc on Sorami City, so Tomoki, via one of Ikaros’s cards, has Sohara grown to giant size to fight the chicken, which she defeats, but then promptly steps on Tomoki for staring up her skirt. The film then switches to Daedalus who explains more about the angeloids and their history, and then to a scene where an angel is asleep in a pod. On Earth, Hiyori Kazane, a resident of Sorami City, and the film’s main heroine, introduces herself and explains how she met, and fell in love with Tomoki, while also narrating about how she took part in several events from the two previous anime seasons, all the while observing Tomoki and his friends, and even becoming acquainted with most of them.

After the recap, Hiyori decides she wants to be closer to Tomoki, so she asks to join the New World Discovery club, though Eishirou is against it, as he remembers seeing an angel resembling Hiyori in Synapse (the same one from earlier in the movie) and is not yet sure what their reality is. He relents however, when Mikako mentions the club's budget will increase with the new addition, which also means Tomoki must now fully participate in the club's activities. Not happy with this, Tomoki decides to make Hiyori quit by subjecting her to various perverted, and fake initiation tests, which Hiyori embarrassingly completes. Despite this, Hiyori’s feelings for Tomoki remain unchanged and she is welcomed in to the club and participates in many activities with them, with even Tomoki accepting her presence and spending much time with her. This makes Sohara, Nymph, and Astraea believe they are dating, but wonder why, so Mikako suggests that Tomoki is blackmailing Hiyori. When the three girls confront Tomoki on this, Hiyori, who overheard everything, clears the misunderstanding and also confesses to Tomoki. Tomoki is left unsure of what to do, while Nymph and Ikaros understand that a relationship between Tomoki and Hiyori is impossible. In Synapse, Eishiro asks Daedalus about the relationship between Hiyori and the angel that resembles her. When she does not answer, Eishiro mentions that when he first met Tomoki, he briefly forgot that they had met and asks if that is related to Synapse, to which Daedalus confirms. Eishiro decides to further investigate, while on Earth Tomoki goes to meet with Hiyori to give her a reply. On the way, Hiyori is run over by a truck and dies, causing her body to disappear and her existence to be erased from the memories of everyone not related to the Synapse. Realizing what is happening, Eishirou desperately runs to where the angels in pods are but when he makes it he does not recognize the Hiyori in the pod. The Master of the Synapse appears and taunts Eishirou with his forgotten memories and mentions that Hiyori is awakening. Tomoki, unaware of Hiyori’s fate, waits for her but when Nymph and Ikaros arrive, the former lies to him and tells him Hiyori will meet him tomorrow. To make up for her lying, Nymph spends the night with Tomoki and asks for the imprinting, but Tomoki explains that he wants her and the other Angeloids to be free. Nymph says she wants to be imprinted because she is in love with Tomoki, but before she can convey her feelings Tomoki experiences severe headaches from the memory wipe, so Nymph holds him, knowing that by tomorrow Tomoki will have forgotten all about Hiyori.

The next morning, Tomoki still clearly remembers Hiyori, while everyone else has forgotten her. Distraught, Tomoki runs over town searching for her, while in Synapse Hiyori is grief-stricken that her time on Earth has ended, so the Master of the Synapse offers her one more chance to see Tomoki. Tomoki confronts Ikaros and Nymph on what is happening, but Nymph explains they cannot tell him anything for fear of Tomoki learning that his reality is not real. Tomoki collapses from the severe headache pain, so the three Angeloids look after him. Nymph picks up something on her radar, so the three go to investigate, and find Hiyori. The reunion is cut short when, she is transformed into an Angeloid and is ordered by the Master of the Synapse to kill the three. Hiyori uses her ability of time manipulation to attack both Sorami City and the Angeloids, and easily overpowers the three. Nymph determines the only way to stop Hiyori is to kill her, though Ikaros objects, but Nymph reluctantly prepares to do so, until she is stopped by Tomoki, who swears to save Hiyori. The Master of the Synapse orders Hiyori to kill Tomoki, but Eishirou arrives to help, while the three Angeloids stall Hiyori. They manage to destroy the structure that binds her, but it does not free her, and Nymph also realizes that the self-destruct system on Hiyori's collar has been activated. Unable to stop the process, Ikaros traps Hiyori within her Aegis to contain the blast, but also traps herself in since she does not want Hiyori to be alone in her final moments. Tomoki however hang glides to them and is let into the Aegis, where he is able to bring Hiyori back to her senses. Hiyori begs for them to get away as it won't be long before she self destructs, so she uses her hacking abilities to dispel the Aegis, and kisses Tomoki before leaving. She thanks him and remembers how they met first met as children, and that it was because of him that she came to love Sorami City. She notes that while her time on Earth was short, she enjoyed her time with everyone and thanks her friends and Tomoki, and reaffirms her love for him before being destroyed. Tomoki breaks down in tears, and the film ends with him swearing that he will never forget Hiyori.

Near the end of the credits, Sohara is seen viewing the scrapbook, filled with pictures of the group having fun. As Sohara leaves, a picture where Hiyori had faded away due to the Synapse's deletion, is seen where Hiyori slowly fades back in, revealing that she has somehow been revived.

In a post credits scene, Tomoki stands at the spot overlooking the city where he and Hiyori first met, and behind him a ray of light shines down with feathers falling from the sky, when he looks he smiles happily, and as the screen fades out, the sound of Hiyori's bell ornaments are heard, also, implying she was somehow revived.

Trivia

 * An interesting note is that in the Hiyori arc of the manga, Kazane Hiyori survives the ordeal and even comes back to school with Tomoki and the others. In the manga, she quits the club and only makes appearances from time to time. In the movie, she dies in the final battle. At the end of the final credits, her face fades back into the picture that was taken earlier in the movie, suggesting she is alive again. After the ending credits, it is also suggested Hiyori is again alive, as if she has taken another form or has otherwise entered their reality once again.
